Expert Solution

Magnetic susceptibility is a measure of how easily a substance is magnetized in a field. The magnetic susceptibility of a magnetic substance is defined as the ratio of the intensity of magnetization to the magnetic intensity .

Where is the intensity of the magnetization and is the magnetic intensity. Magnetic susceptibility has no unit because the unit of and is same .

Intensity of the magnetization is defined by:

Where is magnetic moment and is the volume of the solid.

Magnetic intensity is defined by:

Where is the magnetic field and is the permeability of space.

Magnetic susceptibility from the equation (1) and (2):

From above equation, we can conclude how magnetic susceptibility changes with different magnetic behaviors in the solid.

As the magnetic field increases the magnetic susceptibility decreases because .
As the volume of the solid increases the magnetic susceptibility decreases because .
As the magnetic moment increases the magnetic susceptibility increases because .
